The audio engine also has been enhanced from previous versions.
As in previous versions of the Engine sound system is implemented in a separate module with the help of OpenAL library.
Besides positional audio, which is already included in the past, we have added the ability to set Pitch of sound sources.
This means, for example, that you can associate the pitch of the sound source of a car engine with the number of engine rotations per minute, the result will be that when the car increases speed, the sound produced by the engine becomes increasingly acute.
Another major upgrade to the audio engine is the ability to manage the blending (i.e. mixing) between more music tracks.
In S2ENGINE HD you can mix up to 4 tracks of music. This system can switch from one music track to another gradually.
